Assessment of various Hamiltonian partitionings for the electronic structure problem on a quantum computer using the Trotter approximation
Luis A. Martínez-Martínez, Tzu-Ching Yen, Artur F. Izmaylov
Solving the electronic structure problem via unitary evolution of the electronic Hamiltonian is one of the promising applications of digital quantum computers. One of the practical…
Growth reduction of similarity transformed electronic Hamiltonians in qubit space
Robert A. Lang, Aadithya Ganeshram, Artur F. Izmaylov
Accurately solving the electronic structure problem through the variational quantum eigensolver (VQE) is hindered by the available quantum resources of current and near-term device…
Quantum Kinetic Rates within the Nonequilibrium Steady State
Loïc Joubert-Doriol, Kenneth A. Jung, Artur F. Izmaylov +1
The nonequilibrium steady state (NESS) of a quantum network is central to a host of physical and biological scenarios. Examples include natural processes such as vision and photosy…
Fluid fermionic fragments for optimizing quantum measurements of electronic Hamiltonians in the variational quantum eigensolver
Seonghoon Choi, Ignacio Loaiza, Artur F. Izmaylov
Measuring the expectation value of the molecular electronic Hamiltonian is one of the challenging parts of the variational quantum eigensolver. A widely used strategy is to express…
Reducing molecular electronic Hamiltonian simulation cost for Linear Combination of Unitaries approaches
Ignacio Loaiza, Alireza Marefat Khah, Nathan Wiebe +1
We consider different Linear Combination of Unitaries (LCU) decompositions for molecular electronic structure Hamiltonians. Using these LCU decompositions for Hamiltonian simulatio…
Improving quantum measurements by introducing "ghost" Pauli products
Seonghoon Choi, Tzu-Ching Yen, Artur F. Izmaylov
Reducing the number of measurements required to estimate the expectation value of an observable is crucial for the variational quantum eigensolver to become competitive with state-…
